WEDGE-FORMING MACHINE.

Specification of Letters Patent.

Patented April 20, 1909.

To all whom it may concern:

Be it known that l, WILLIS W. KRUTsoH, a citizen ol the United States, residing at Co'l'leyville, in the county of Montgomery and State of Kansas, have invented certain new and useful Improvements in Till/*edge- Forming Machines, of which the following is a specification.

My invention relates to improvements in wedge forming machines; and my object is to produce a machine of this character whereby wooden wedges may be rapidly and perlcotly formed without waste of material. The machine is adjustable so that wedges of diflerent lengths may be produced on the same machine.

Referring now to the accompanying drawing, which illustrates the invention: Figure 1 represents a plan view oi' my machine. Fig. 2 is a vertical longitudinal section on line ll-ll of Fig. 1. Fig. 3 is a broken inverted plan view of the machine. Fig. 4 is a broken section on the plane of line ll-ll of Fig. 1. Fig. 5 is a cross section on line V-V of Fig. 2.

ln carrying out the invention l employ a `frame consisting of two longitudinal bars 1, which may be firmly secured to a base 2, or they may be secured directly upon a workbench. 3 designates a cross-head reciprocably mounted in said frame, the sides thereof operating in grooves l` in the lower portions of bars 1.

5 designates a gage carried by cross-head 3, it being adjustably secured thereto by bolts 6 and 7, so that its forward end may be raised or lowered, and thus regulate the length and thickness of the wedges to be'produced. Gage 5 is provided at its upper portion with a shoulder S and at its lower portion with a transverse lug 9, which latter is seated in the bottom of a V-shaped groove 1() in the upper portion of the cross-head, so that the gage may rock therein while being adjusted.

11 designates a transverse groove in the gage at the bottom of shoulder 8, adapted to receive the cutting edge of a blade 12, which is adjustably secured to the rear portion of the frame by screws 13 14, so that its rear end may be tipped up suiliciently to clear the wedges as they are cut from a block.

The gage and the cross-head are actuated by a hand-lever 15 through a connecting-bar l 16, pivotally secured at its ends to the gage and the hand-lever.

In practice a block of wood is placed upon the inclined portion 17 of the gaffe with its rear end abutting against shoulder 8, as shown by dotted lines in Fig. 2. Lever 15 is then swung forward to carry the crosshead and the gage forward to push the block against blade 12, which cuts through the block in a horizontal plane, and thus forms a wedge 18, see Fig. 4. The rear side of groove 11 is prevented from contacting with the cutting edge of the blade by the forward end of the cross-head, which contacts with the end of grooves 4.

From the above description it is apparent that I have produced a simple machine whereby wedges may be quickly and cheaply produced, and while l have shown the preferred form of my invention, l, of course, reserve the right to make such changes as properly fall within the spirit and scope of the invention.

Having thus described my invention, what I claim is 1. A wedge l'orming machine embodying a frame, composed of a base, a pair of grooved longitudinal bars on said base, a cross head sliding in said grooves of the bars, said cross head being formed with a transverse V- shaped groove, a gage having a transverse lug on its bottom which seats in said V- shaped groove, bolts secured to said cross head and said gage extending on op osito sides of said lug and groove thereof, saic gage on its upper face being formed with a shoulder and a groove at the bottom of the shoulder, a cutting blade secured to said frame bars adapted Yto have its cutting edge extend in said last named groove of the gage, and means whereby the cross head may be operaten.

2. A wedge forming machine embodying a frame, a cross head reciprocatingly mounted in the `frame, said cross head being 'l'ormed with a transverse groove on its upper l'ace, a gage having a transverse lug on its bottom i'ace which seats in said groove oll the cross head so as to be capable oll having a rocking movement therein, bolts secured to said gage and cross head extending on opposite sides of said groove and lug, and a cutting blade on the frame.

3. A wedge forming machine embodying a frame, a cross head mounted to reciprocate therein, a gage overlying Ysaid cross head, means disposed central of the length `of said gage and cross head ,vhereby the may have rocking movement with respect to the cross head, means on opposite sides of said lirst named means to secure said gage in its adjusted position against movement with respect to said cross head, a cutting blade,

and means whereby said cross head may be reciprocated.

fl. A Wedge forming machine embodying a frame, formed with longitudinal grooves, a cross head ilor .reciprocating movement in said grooves, a cutting blade secured. to said frame, a gage on said cross head, said gage being formed 'with a shoulder and with a groove at the base oll the shoulder into Which the cutting edge ol' the blade is adapted to project, said cross head having one of its ends for engagement with the end walls formed by said longitudinal grooves of the trame at one end oi' the latter to restrict the extent of projection of the cutting edge o'l' the blade into said groove of the gage, and means whereby said cross lhead maybe recprocated.

5. A Wedge forming machine embodying' a lrame, vertically adjustable screws carried by the iframe, a cutting blade having its rear end on its bottom face seating kon the upper ends of said screws, second screws which pass through said blade and into the frame, the cutting edge ol` said blade being supported at its ends by engagement with the frame, -a cross head, a gage carried thereby, and

lmeans to impart reciprocating movement te said vcross head.

ln testimony Wl'rereoi l aihx my signature, n1 the presence ol ltwo Witnesses.
